2015 Ford Fiesta doesn't have central locking

[Caitlin B]

Hi,

I've recently bought a 2015 Ford Fiesta in July, it's come to my attention that my car doesn't have central locking, the keys that was given when I bought the car aren't the keys for central locking, I have to unlock my car by placing the key into the drivers door handle, I'm wondering if there's anyway I'll be able to get central locking installed that won't cost me an arm & a leg.
